Since the invention is illustrated in its application to a well-known type of machine characteristic features of which are fully shown and described in various prior United States Letters Patent, includingespecially the Letters Patent hereinbefore mentioned, only those portions of the machine which it is necessary to refer to particularly for an understanding of the invention are shown .in the drawings and will be described in detail.

The machine is provided with a toe gripper 10, shown in dotted lines in Fig. 1, and with opposite side grippers 12 (Figs. 1 and 2) for pulling the upper over the last at the end of the toe and at the opposite sides of the forepart. It will be understood that these grippers are operated by power to pull the'upper, after which the machine comes automatically to a stop with the several grippers holding the upper under tension. Thereafter, in the further operation of the machine, the margin of the upper about the end of the toe and along the sides of the forepart is laid inwardly over a sole on the last and is fastened in overlaid position. The machine illustrated is a machine of that type having overlaying means constructed to wipe the upper into lasted position about the toe and commonly used in the manufacture of turn shoes. For this purpose, it is provided with toe-embracing wipers comprising plates 14 of substantially the saine construction as shown and described in Letters Patent No. 1,406,260, granted upon my application on February 14, 1922. These wipers are mounted to swing laterally of the shoe and are carried by a front arm which is mounted for swinging movement lengthwise of the shoe in a manner characteristic of machines of the type illustrated, the lower end portion of this arm being shown in section at 16 in Fig. 1. The portion of the arm thus shown is so constructed as to serve as a tacker for driving an upper-holding tack substantially midway between the opposite sides of the end of the toe. The front arm also carries two other tackers 18 which may be termed the outside tackers of the group of three taclers thus provided for driving tacks at the end of the toe. These two tackers are so mounted on the arm as toppermit either one to be adjusted independently of the other either lengthwise or laterally of the shoe. The means whereby they are thus mounted is not shown in detail, since it is of substantially the saine construction as shown .in Letters Patent No.,A 1,280,613. The position of each outsideV tacker 18 laterally of the shoe is determined by a screw 20 threaded therein with its inner end in engagement with the central tacker 16. For adjusting each of these tackers lengthpivoted at 24 to a block 26 which is secured te the tacker, this rod extending through a member 28 which is fast on themiddle tacker 16 and having a nut 30 threadedon its outer end and engaging th-e member 28. Between the member 28 and the block 26 is a spring 32 which tends to move the tacker in one direction while the nut 30 may be utilized in opposition to this spring to move it in the opposite direction. By 18 may be adjusted lengthwise of the shoe relatively to the central tacker 16 to vary the locations of the tacks in accordance with differences in the contours of different styles and sizes.

Mounted for swinging movements laterally of the shoe at the opposite sides of the forepart, as usual in machines of the type illustrated, are side arms 34, only one of which is shown in the drawings, each of these arms having mounted thereon a group of four tackers 36, 88, 40 and 42 for driving upperfastening tacks at the reai' of the toe end tacks. The tacker 36 is fast on the arm 34,

while the other three taclrers are mounted on a rod 44 on the arm for swinging movements laterally of the shoe to permit them to adjust themselves in accordance with the position of the toe wipers 14 at the end of the overwiping operation. To assist in controlling these swinging taclrers while permitting them to move relatively to one another as described. there is fast on the arm 34 a rod 46 which extends through slots in these taclers, as shown in Fig. 1. a rod 50 which is fast on the tacher 36 tends to swing the tacker 38 inwardly toward the shoe as far as permitted by the rod 46 and is yieldable tov permit the tacker to adjust itself as this means the two tackers of the toes of shoes A spring 4S mounted on .Q0 wise of the shoe, there is provided a iod 22 described. The two tackers 40 and 42 are similarly controlled by opposite ends of a spring 52 on the rod 50. It will be understood that each of these side tackers, and

likewise each of the toe tackers hereinbefore described, includes a pair of tack tingers 54 and a tack driver' 56, the severaldrivers of each group of tackers being operated by a driver bar on the corresponding supporting arm, substantially as shown in Letters Patent No. 1,280,613. The driverbar for operating one of the group of side tackers is shown at 58 in Fig. 2.

By reference to Figs. 1 and 3 it will be seen that the tacker 38 is spaced from the relatively fixed tacker 36 by a collar 60 on the rod 44 and another collar 62 lon the rod 46. These two tackers are thus permanently positioned to drive their tacks at an invariable distance from each other lengthwise of the shoe. For purposes of this invention, the other twotackers 40 and 42 are mountedfor rectilinear adjustment a-s a unit lengthwise of the shoe relatively to the tackers 36 and 38. Such adjustment is eifected by sliding the tackers 40 and 42 along the rods 44 and 46, these tackers being spaced apart by a collar 64 on the rod 44 and a collar 66 on the rod 46. Springs 68 and 70 mounted on the rods 44 and 46, respectively, tend' to slide the pair of tackers 40 and 42 forwardly on these rods, andthe position of these tackers with respect to such sliding movement is determined by a clamp member 7 2 adjustably secured to both rods by means of clamping screws T4 and`76. Accordingly, when itis desired to make any adjustment of the foremost pair of side tackers, the operator loosens the clamp member 72 and positions it in a different location on the rods 44 and 46, according to the adjustment desired. lt will be understood that the springs 68 and 70 hold the two adjustable tackers in the positions lengthwise of the rods determined by the clamp member 72, and that these springs also act to hold the tacker 38 yieldingly against the collars 60 and 62, these springs being arranged to engage suitable bearing plates in engagement with the tackers 38 and 40. lt will be further understood'that the operative relation between the driver bar 58 and the drivers 56 of the adj ustable tackers is not affected by their adjustment, since the driver bar carries a cross-rod 78 (Fig.i2) for operating these drivers and alo-ng which the latter are adjustable.

rlhe tacks are conducted to the tack fingers 54 through a slot 8() in each of the several tackers, as common heretofore. Tacks are fed to the rearmost tackers 36 and 38 of each group of side tackers through tubes 82 the lower ends of which are mounted in a block 84secured to a bracket 86 fast on a supporting bracket 87 on the side of the machine. For feeding tacks to the adjustable tackers 40 and 42 there are provided flexiblev tubes 88 the lower ends of which are mounted ina l 90fis provided with a bolt 92 which extends through a slot 94 in the bracket 86, this bolt having thereon a nut196 for clampingv the block 90 in adjusted position. i

It will be understood that in the operation of the overlaying and tacking means, as in prior machines of the general type illustrated, the toe wipers 14 are moved lengthwise ofthe shoeby the front arm and are closed inwardly over theside edges ofthe shoe bottom bythe side arms, and that after the margin of theupper has been wiped inwardly by these wipers the tacks are driven by the several tacker-s in the relative locations deterinined by previous adjustments of the tackers. rlhe machine shown is further provided with means on eachside `arm 34 for clamping the margin of theupper against the sole at the rear of the several side tackers. ri'fliis means comprises a` clamp member 98 so mountedas to permit it to Vslide laterally of the shoe and to tip height-wise ofthe shoe relatively to the arm`34 under control of a plate 100 and la spring 102, substantially as disclosed. in Letters Patent No. 1,396,005,

Granted on Nov. 8. 1921 u son an invention of I 1 Orrell Ashton.- v The provision for adjustment of the foremost pair of each group of side tackers, as above described, is especially useful in adapting the machine to operate with most `satisfactory results on shoes' of different styles. As hereinbefore explained, .the twol outside tackers 18 of the group ofA toe end tackers are adjustable relatively tothe middle tacker 16 to position the tacks driven thereby in accordance with the contour of the end of the toe, and it will be evident .that in operating on shoes having comparatively square toes, the tack'ers 18 mustjbe so adjusted that the tacks driven thereby are morevnearly in line with the central toe tack across the end of the toe thanV vin operating on shoes with narrow, pointed toes. Itis under suchviconditions Athat the means providedby this invention for adjusting the foremost side tackers lengthwise of the shoe is especially advantageous, as serving to avoid undue spaces between the toe end .tacks and the side tacks at whatmay be termed the-corners ofthe toe where the curvature of the edge of the shoe bottom is pronounced and where, accordingly, rthere is danger that prominent wrinkles may form in the margin of the'. upper.` if the tacks are driven toe far apart. -It will be understood thatthe resulting variationrin the spacing between the two tacks driven by the side tankers 38 and .40 is unobjectionable,.since in the locations where these spaces occur the curvature .of the edge ofthe shoe bottom is not profas nounced and objectionable wrinkles are therefore unlikely to form.

In Fig. 1 the parts are shown in the posi- .tions which they occupy at that time in the cycle of the machine when the toe wipers-14 have wiped the upper inwardly over the sole and are in pressing engagement with the upper, at which time the upper-fastening tacks are driven. Itis considered that in operating upon some` shoes, especially shoes of that kind in which the uppers are made of comparatively heavy leather, improved results are yobtained if the machine comes to a stop at the timev when the wipers are thus in pressing engagement with the upper, in order to permit them to have more of a molding effect upon the upper than if they were immediately Withdrawn from the shoe after the tacks are driven. On the other hand, in operating upon shoes made of lighter leather,

such a stop may be unnecessary and may well be omitted for the sake of greater speed in the operationy of the machine. The machine herein shown is, accordingly, provided with means which may be utilized at will-to cause the machine either to come to a stop at the above-mentioned point in the cycle or to omit such a stop. This means is illustrated in detail in Figs and 6 in its relation to the type of automatic `controlling mechanism characteristic of machines such as shown in the Letters Patent hereinbefore mentioned. Such automatic controlling mechanism is rfully shown and described in Letters Patent No.

I 791,986, granted on June 6, 1905 upon an application of R.V F. McFeely, and accordingly only such parts as it is necessary to refer to for an understanding of the novel means provided by this invention are herein illustrated in detail.

It will be understood that the machine is provided with a main operating cam shaft 104 driven intermittently by al pulley 106 which is controlled by a clutch (not shown), this pulley being connected to the cam shaft 104 through reduction gearing including gear wheels 108 and 110, portions of this gearing being omitted from the drawings. Tostop the machine there is provided a brake shoe 112 for engaging the pulley 106, the brake shoe being fast on a vertically movable rod 114 which is connected at its lower end to the clutch, so that whenthe rod is moved upwardly by a spring 116 the brake is released and the clutch is set to start the machine, and when the rod is moved downwardly the clutch is released yand the brake shoe applied to the pulley to stop the machine. For imparting the downward movement to the rod 114, there is fast on the cam shaft 104 a cam wheel 118 which has on its periphery three cam projections 120, 122 and 124 arranged to engage a roll 126 carried by a vertically movable member or slide 128 which is pressed upwardly by springs 130. The slide 128 has fast thereon 'a lug' 132 arranged to engage an abutment 134 carried by the brake shoe 112 to move the brake shoe and the rod 114 downwardly, the abutment 134 in the construction shown being adjustable by means or' mechanism shown and described in Letters Patent No.'1,771,045granted on Julyv 22, 1930, on my co-pending application Serial No. 89,370, tiled onvFebruary 19, 1926. The abutment 134 is mounted on a horizontally movablel slide 136 on the brake shoe 112 which is pressed toward the left (Fig, 5) by a spring 138. To start the machine, the slide 136 is moved toward the right against the resistance of the spring` 138, far enough to with-'n draw the abutment l134 from under the lug 132, by the action of treadle-operated mechanism not herein shown in detail but fully illustrated and described in Letters Patent No. 791,986, this. mechanism including a member 140 in engagement with the lefthand end of the slide 136. It will be understood that when the abutment 134 is thus moved from under the lug 132, the spring 116 acts to raise the rod 114 with the brake' shoe 112 and the parts carried thereby and thus to start the machine.

When the machine is thus started at the beginning of the cycle, the cam projection 120 is in engagement with the roll 126. Beyond this projection there is a depression 142 in the periphery of the cam wheel 118 which permits a retractive upward movement of the slide 128 in response to the action of the springs 130 far enough to permitthe"` abutment 134 to be returned to a position under the lug 132 by the action of the spring 138. In this manner the parts are so positioned as to render the next cam projection 122 on the cam wheel effective to impart downward movement to the brake shoe 112 and the rod 114 to stop the machine when this projection arrives in position to engage the roll 126. This is the projection customarily provided in machines of the type illustrated to bring the machine to a stop at the end of the upper pulling operation while the grippers are holding the upper under tension. Thereafter the machine is again started in the same manner as before, and be= yond the cam projection 122 is another depression 144 in Ythe cam wheel which permits the parts to assume a relation such as to render the next projection ,124 effective to stop the machine. This is the projection' provided in the machine herein shown for the purpose vof bringing the machine to a stop at the point in the cycle represented by Fig. l when the toe wipers 14 are in pressing engagement with the upper. It will be un-v derstood that thereafter, at the will of the operator, the machine will be again started and will complete its cycle, and that it will be brought to a stop at the end of the cycle by the cam projection 120.

In order to cause the machine to omit the stop effected, as above described, by the pro# jection 124, there is secured in al recess in one side of the cam wheel 118 adjacent tothe depression 144 thereinV a plate 146 having periphery concentric with the axis of the cam wheel and formed to serve as a bridge between the two cam projections 122 and 124. To cooperate with the plate 146 there'is secured to the lug 132, hereinabove described as fast on the slide 123, a bracket 143 which carries a rotatable stud 150 provided with an eccentric pin 152 on which is mounted a roll 154 for engagement with the periphery of the plate 146. T he stud 15() may be turned through an angle of 130 to present the roll 154 either in position. to be operatively engaged by the plate 146, as indicated in Fig. 6, or in an idle position such as to prevent the plate from acting thereon, as illustrated The stud 150 is provided with a slot in its out-er end to permit it to be thus turned by the ruse of a screw driver, and to maintain it in either of its positions of adjustment there is provided a V-shaped pin 156 controlled by a spring` 158 and arranged to enter either of two diametrically opposite recesses formed in the stud, as shown in Fig. 6. It will be evident that when the stud 150 adjusted as shown in Fig. 6, the action of the plate 146 on `the roll 154 is such as to hold the slide 12S in its depressed position during` that part of the cycle corresponding to the interval between the cam. projections 122 and 124. Such retractive movement of the slide 123 as to permit the abutment 134 to be returned to a position under the lug 132 can, therefore, not occur until after the projection 124 has passed the roll 154. Accordingly, the machine will continue its cycle' uninterruptedly from the stoppino` position determined by the projection 122 to the final stopping position determined by the projection 120, omitting the stoii at the point represented by the projection 124. On the other hand, if it is desired to render effective to bringthe machine to a stop at that point in the cycle, the stud 150 is turned through an angle of 180 to lower the roll 154 below the upper surface of the main roll 126, as shown in Fig. 5. llVith the roll 154 in this position the `plate 146 has no effect on the slide 128, and consequently the main roll 126 will be received in the depression 144 of the cam wheel in response to upward move ment of the slide 128, so that the abutment 134 will be returned to a position under the lug 132 in time to render the cam. projection 124 effective to bring the machine to a stop by its action on the roll 126. Simple and conveniently operable means thus provided for causingl the machine to come automatically to a stop at the point in the cycle represented by Fig. 1 or to omit such a stop at the will of the operator. v i
